The control flow elements—tasks and containers—for building the control flow in a package. Control flow elements prepare or copy data, interact with other processes, or implement repeating workflow. Precedence constraints sequence the control flow elements into an ordered control flow and specify the conditions for executing tasks or containers.

The data flow components—sources, transformations, and destinations—for building data flows in a package that extract, transform, and load data. Paths sequence the data flow components into an ordered data flow.

The variables that can be used in expressions to dynamically update column values and property expressions, control execution of repeating control flows, and define the conditions that precedence constraints apply.
